The outputs are re-activated based on the load applied as soon as device initialization is
concluded.

The output is de-activated automatically in accordance with the given trip curve. The
device then switches to Status 4.

After a defined waiting period (cooling time), the output switches to Status 5. The
remaining time of the waiting period is saved when the device is switched off. This time
must first elapse when the device is switched on again. This feature protects the switching
elements against any overloading.
